难解性的K-归约的概念;然后给出了一个从MAX 3SAT问题到MAX 3SAT-2问题K-归约.因为逼近MAX 3SAT问题在某个常数因子内是计算难解的,所以逼近MAX 3SAT-2问题在某个常数因子内是计算难解的.这样作为推论也可以得到逼近MAX 3SAT-3问题在某个常数因子内是计算难解的,简化了以前关于逼近MAX 3SAT-3问题难解...
We study the complexity of approximating Max NM-E3SAT, a variant of Max 3SAT when the instances are guaranteed to not have any mixed clauses, i.e., every clause has either all its literals unnegated or all of them negated. This is a natural special case of Max 3SAT introduced Gurusw...

摘要: In this paper I present a MAX2SAT algorithm based on the randomized algorithm of Papadimitriou from 1991. We also show that this algorithm finds a solution (if it exists) for a MAX2SAT problem equivalent to a 3SAT problem with high probability in polynomial time. 年份: 2017 收藏...
As a first application, we prove the Max NP-completeness of Max 3Sat without using the PCP theorem (thus solving an open question posed in Khanna et al., 1994). Successively, we show that the “planar” restrictions of several optimization constraint satisfaction problems admit linear-time ...
